I've been away from the forum for a couple weeks, so just saw the above couple posts about stabilizing with K-meta and sorbate, then backsweetening. That works fine if you're kegging, or if you don't want a fizzy graf or cider. But if you bottle like I do, and want to backsweeten AND carbonate, then I've found the best technique is the cooler pasteurization. There's a thread somewhere in this section of the forum, but the 2 second version is to bottle one in a soda bottle and when that one is turgid and to your liking then the rest are also ready. Put them in a cooler and add hot tap water to prewarm. Meanwhile, heat 3-4 gallons to 170*. Drain the tap water and add the 170 water. Cover and let sit for 10 minutes (or longer if you're lazy). Voila, done.
